24100a
Abstract
Understanding the reaction mechanism of carbon formation is required in order to find solutions to avoid catalyst deactivation during the partial oxidation methane for syngas (H2 and CO) generation, required in Fuel Cells. The research presented in this proposal has the objective to study the role of oxygen vacancies of oxygen ion conducting catalysts and hexaluminates in the partial oxidation of methane and identify the nature of the oxygen species, such as surface lattice oxygen ions or adsorbed oxygen, in the oxidation of carbon species during the partial oxidation of methane. Results of this research may provide the guidelines in the design and synthesis of catalysts to mitigate carbon formation. These experiments will complement previous tests performed with 18O ceria labeled catalysts. It will be required to measure 18Oxygen concentration as a function of catalyst depth prior and post reforming catalytic tests. New materials, such as pyroclores and hexalumi-nates, will be studied.
The specific objectives of this proposal are:1) Prepare 18O label catalysts 2)conduct tests in a catalytic flow reactor. 3)Determine 18-O reaction (NRA) spectra of catalysts by obtaining yield as a function of channel number. (4) Use the SIMNRA simu-lations code to fit the NRA data (5) Determine the amount of oxygen-18 as a function of catalyst depth.
